VAPOBIZER.

Specification of Letters Patent.

Patented June 24., 1913.

Application filed February 24, 1913. Serial No. 750,310.

To all whom it may concern:

Be it known that I, THOMAS Bnoous, a citizen of the United States of America, residing at Cedar Springs, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Vaporizers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in Vaporizers, and its object is to provide a device of this type which will successfully vaporize the less volatile hydro-carbon fuels such as kerosene, crude oil, etc., and to mix the same with the proper quantity of air to form a combustible gas, to provide a device which is compact and simple in construction and to provide the same with various other new and useful features of construction and arrangement as hereinafter more fully de scribed and particularly pointed out in the claims, reference being had to the accompanying drawing which represents a vertical sect-ion of a vaporizer embodying my invention, said section being taken through the axis of the device.

1 represents a metallic base member cuplike in form and provided with a central supporting member 2 preferably castinteral iway from the walls thereof and supported by bosses 3. An air induction passage 4 is provided on the said base member and communicates therewith, and avalve 5 is provided in this passage and adapted to be manually adjusted to control the quantity of air admitted into the base member.

A metallic head member 6, substantially the form of an inverted cup is located above the base member and spaced apart therefrom, and said head member is provided with a supporting member 7 similar to the one located in the base member and likewise spaced away from the sides of the head member and supported by bosses 8, several of which may be located at intervals around the sides of the said member. An outlet passage 9 is provided in the upper side of the head member and flanges 10 provided with bolt holes adapt this head member to be attached to an eduction pipe. 1

The body of this device is preferably formed of a plurality of tubes 11 12, 13, 14 and 15, these tubes being preferably made with the said base member, but spaced of glass and are concentrically arranged and spaced apart, forming a series of concentric annular chambers. The tubular members are interposed between the base and head members 1 and 6 and their respective ends are let into concentric annular grooves turned in the respective upper and lower faces of said base and head members,

the outer tube 11 being supported by the rims of. the base and head members while supporting members 2 and 7.

The annular passage 19 which isformed between the outer tube 11 and the next inner tube 12, serves as an air passage and com municates directly with the cuplike interior of both base and head members, and air passing in through the induction passage 4 will freely pass through the base member and through the said annular passage 19,

I the rest of the tubes are supported by the into the head member and through they eduction passage 9.

The fuel to be vaporized is taken in through a pipe 20 which communicates with a passage 21 extending through one of the bosses 3 in the base member, and which leads into the lower end of the chamber 18 formed between the tubes 12 and 13. The tube'13 which forms the inner wall of this chamber, is provided at its upper end with a series of openings 22 which allow the fuel to pass into the next inner chamber 17 of the series, this chamber being formed between the tubes 13 and 14 and the tube 14 which forms the inner wall of this chamber has a coil of wire 23 wound about it, this winding preferably being commenced at the upper end of the tube and continued spirally through out its entire length, and the wire at the lower end of the tube passing through an opening 24 therein and thence wound about the inner tube 15 of the series spirally toward the top thereof. Both ends of the wire are passed out through the head-0f the device and connected in an electrical circuit. The wire 23 which is used to form the coils about these tubes is preferably of German silver or some material having high chamber 16, through a series of openings 24 provided in the lower end of the tube 13, it

then follows the inner coil in the chamber 16 upward and by the time it has reached the upper end of this chamber the heat from the coils has transformed it into a gaseous state and it passes out of this chamber 16 through a passage 25 in the head of the device to the needle valve 26 which communicates with the outlet passage 9. After passing through the needle valve, this gas mines with the air which flows through the passage 19, forming a combustible mixture, and then out of the eduction passage 9 to any source of utilization.

When the device is used in connection with an internal. combustion engine the inlet passage l of the device is preferably connected by tubing, to a chamber surrounding the exhaust manifold of the engine or to any source from which heated air may be obtained, and this heated air as it is drawn in through the passage 19 which surrounds the inner tubular chambers which contain the fuel, aids in heating the fuel contained therein and also tends to maintain the vapor ized fuel in its gaseous state after it has been mixed with the air.

The valve 5 in the air passage may be adjusted to admit the proper amount of air and the needle valve-26, the stem of which extends downward through the central tube 15 and projects through the lower side of the base member, is adapted to be manually adjusted to control the passage of vaporized fuel therethrough, and l have found that the manipulation of this one valve is all that isnccessary to control the mixture.

l Vhen used in connection with an internal combustion engine using electrical ignition l[ have found it expedient to utilize a partof the electrical current furnished by the ignition apparatus to heat the coils of wire in this device. This feature however, is optional, as any source of electric current will answer the purpose equally well.

lVhatl' claim is I 1. In a fuel vaporizer, a body having a series of concentric annular chambers one of which serves as an air passage and communicates with an educt-ion pipe and the remainder of the said concentric annular chambers being intercommunicable aiid serving as fuel chambers, and also being in communication with the said air passage, an electrical heating unit in one or more of said fuel chambers, and means for supplying the fuel chambers with hydro-carbon fluid.
